Patented Mar. 18, 1941 UNITED STATES PATENT OFFICE PROCESS OF MANUFACTURING POTTERY WITH INCISED OB INCRUSTED DESIGNS 3 Claims.

This invention relates to a new and improved process of manufacturing decorated chinaware and pottery with incised or incrusted designs on the surface thereof. F

The invention consists of the new and novel process hereinafter set forth in the following specification, and pointed out in detail in the appended claims.

In the accompanying drawing:

10 Figure 1 is a plan view of a plate formed of clay, or other suitable material, before being baked and having stencils placed thereon ready for spraying.

Figure 2 is a similar view to Figure 1 with the 15 stencils removed after the spraying process and showing the incised design.

Figure 3 is an enlarged section taken on the line 3-3 of Figure 2.

Figure 4 is a plan view of a plate before being baked and having a number of cut out stenci placed thereon.

Figure 5 is a similar view to Figure 4 with the stencils removed and showing the incrusted design thereon.

Figure 6 is an enlarged section taken on the line E--6 of Figure 5.

Referring to the accompanying drawing, forming part of this specification, like reference numerals designate like parts throughout the several views thereof. The process of forming the designs is carried out by first forming a plate, or other article, of clay, or other suitable material, and when the same has dried sufficiently to be handled, but before being thoroughly dry, the stencil l which is formed of rubber or rubberized material, is dampened and placed upon the surface of the plate 2 upon which the design is to be formed. The clay, or other material of which the design is to be formed, is made up in a liquid 40 or semi-liquid condition and is sprayed over the entire upper surface of the plate 2 and the stencil I, and when this is partly dry, but before it becomes hardened, the said stencil I is removed, leaving the incised design 3, as shown in Figures 2 and 3 of the drawing. When thoroughly dry, the article is baked after which a coating of glazing material is applied to the article, either by dipping or spraying the same thereon, and the article is again baked, leaving a thoroughly glazed 5 surface on the finished article. The clay, or other material that is blown upon the article as the design is being formed, may be of any suitable color.

In Figures 4, 5 and 6, I have shown the process of forming an incrusted design on the article which, in the present instance, is a plate. The incrusted design is formed by placing cut out stencils 4 on the plate, as shown in Figure 4 of the drawing, and the liquid or semi-liquid clay is brushed or blown through the stencils 4, and when it has set sufliciently, the said stencils 4 are removed, leaving the incrusted designs 5, as shown in Figures '5 and 6 of the drawing. The article is then baked andglazed and finally baked, as described for the incised design.

Having thus described my invention, what I claim is:

1, The new and useful process of manufacturing decorated chinaware and pottery in the clay state consisting of first forming the article of clay, or other suitable material, then placing a stencil upon the article to be decorated, then spraying or otherwise coating the surface of the said article with clay, or other suitable material, in a semi-liquid condition while the article is still in the raw or unbaked state, and after the latter is sufiiciently set, removing the stencil and baking the article in the usual manner.

2. The new and useful process of forming decorated chinaware and pottery consisting of first forming the article to be decorated, then placing a stencil upon the said article and then forcing clay, or other suitable material, in a semi-liquid condition through the stencil, forming an incrusted design, then removing the stencil after the clay is thoroughly set, and then baking it in the usual manner.

3. The herein-described process of manufacturing decorated chinaware and pottery in the clay state consisting of first forming the article of clay, or other suitable material, then placing thereon a stencil, then spraying clay, or other material, in a semi-liquid condition over the surface of the article which is still in the raw or unbaked state, and after the clay, or other material, has set sufiiciently, removing the stencil, then baking the article and after being thoroughly baked, applying a glazing material by spraying, or otherwise, to the article and then again baking in the usual manner.
